To all whom it may concern: I

Be it known that I, IRVIN L. BOLINGER, a citizen of the United States, and a resident of Chicago, in thecounty of Cook and State of Illinois, have invented a certain new and useful Improvement in Cattle-Guards, of which therfollowing is a specification,

This invention relates to cattle guards and relates particularly to cattle guards made from sheet metal provided'with teeth struck or stamped up from said metal.

The object of the invention is to provide a simple in construction, strong and durable, and which shall be relatively cheap in construCtionQ To this end, a cattle guard of my invention comprises the various features and details of construction hereinafter described and claimed.

- .Figure 1 is a top plan view of a cattle I guard of my invention shown as applied in use. Fig. 2 is a side view thereof. Figs. 3 and 4 are enlarged fragmentary sectional views taken substantially'onthe lines 33 and H, respectively, of Fig. 2, illustrating the manner of securingthe plates on which the teeth are formed to the intermediate cross supports therefor; and-Fig; 5 is a fragmentary perspective view, on an enlarged scale, of one of the plates on which the teeth are formed.

Referring now to the drawings, A designates the rails of a railroad tracksand A the ties on which said rails are supported.

As shown in Fig. I of't'he drawing's,'in* which I have shown my improvedcattle guard as applied in use, said guard comprises a plurality of sections, the finished guard preferably consisting of four sections comprising guard sections on both theinner and outer sides of each rail, andthe width of said guard sections being equal to half the distance between the rails, so that said guard sections will entirely fill the space between the rails. Each guard section consists of a plurality of separate bars or plates 1 of suitable sheet metal, preferably sheet steel, the

ends of which are rigidly secured to transverse members 2, which are designed to rest upon the track ties, and which are preferably formed by means of suitable sheet metal plates or bars bent lengthwise, to form webs 3 and 4, the ends of the tooth bars 1 overlapping the webs 4 and being secured there- Specification of ilet'tersflr'ateiit,

to in: any suitable. manner, as by rivets, and

the webs 3 beingdisposed in substantially vertical positions and. extending approximately at right angles to the webs 4. Said the tooth plates 1 in such manner as to leave continuou's webs 6 a't-"each side of said I toothbars which are turned down substanti'ally at right vangles to the planes of said tooth bars to form depending marginal .ribs or flanges 'Gatthe edges of said tooth bars.

While in Fig! .1 of the drawings, onlytwo 1 j of said plates. -1 at each side'of the guard are shown s to'othed,as constructed, all of said plates wllljbe toothed. Said ribs or flanges will greatly reinforce and strengthen said "tooth; plates considered separately, andcollectively will impart such strength to the guard sections that they will easily sustain the weights to which, they will besubjected l/Vhilemy invention contemplates the use i t'ionlat opposite sides' oredges of the tooth barsl substantially in the planes of the depending marginal ribs or flanges 6. v Between their ends, the" tooth bars-l are braced and strengthened by suitable trans verse supports consisting, as shown, of angle bars 7 to whlch the marginal ribs or flanges 6 on the tooth bars 1 are rigidly con-'- nected, and which may be conveniently formed by plates or bars of sheet steel bent into proper form. In the preferable constructionshown, the tooth bars 1- are conj I nected to said angle bar-supports 7 in the following manner.:Formed transversely in, said angular supports at proper intervals to receive the marginal ribs or flanges 6, are slots 8, said slots being of such depth that the lower edges of said ribs or flanges will; bear upon the bottoms of said slots, as shown in Fig. 3 of the drawings. After said marginal ribs or flanges 7 have been inserted into the slots 8, they are swaged laterally, 1

preferably inwardly, as shown at 9, whereby they Will be interlocked With the angular supports 7 at the inner edges of said slots. Said transverse supports 7 Will operate both to brace the tooth bars laterally and to connec't or tie said tooth bars together to form a unitary structure With said transverse supports in such manner that a load imposed on one part thereof Will be distributed and sustained by adjacent members.- So

10 strong is my improved guard, in fact, that I have been able to dispense with the use of extra length ties as a foundation for said guards and to use ties of standard length, letting the extreme edges of the outside guard sections overhang, Without danger of breaking or bending under any usual loads Which they sustain in use.

.1 claim:..

1. A cattle-guard comprising a plurality of spaced tooth bars provided with marginal I flanges, the teeth on said bars being formed from the portions of said bars between the flanges and comprising spaced series of teeth arranged substantially in the planes of said marginal flanges thereon, substantially as described. r

, 2. A cattle guard'comprising transverse end frame members, and a plurality of spaced tooth bars secured to said end frame memhere, the lateral edges of -said tooth bars bein bent to form mar inal flan es and the teeth on said bars being formed from the POTlllOIlS of said bars between the flanges and comprising spaced series of teeth arranged substantially in the planes of said marginal flanges thereon, substantially as described.

3. A. cattle-guard comprising transverse end frame members, a plurality of spaced tooth bars secured to said end frame mem-- 40 bers, thelateral edges of said tooth bars be- Gopi es of this patent may be obtained for termediate said end frame members provided With slots Which receive the marginal flanges on said tooth bars, and means for connecting said tooth barsand intermediate transverse supports, substantially as described.

4. A cattle-guard comprising transverse end frame members, a plurality of spaced tooth bars secured to said end frame mem bers, the lateral edges of said tooth bars be ing bent to form marginal flanges thereon, and a transverse angle bar or bars intermediate the end frame members, said angle bar orbars being provided With slots Which receive the marginal flanges on said tooth bars and the portions of said marginal flanges Which engage said slots beingsvvaged laterally to interlock said ribs or flanges With the sides of said slots, substantially as described.

5. A'cattle-guard comprising'end frame members, a plurality of spaced tooth bars secured to said end frame members, the lateral edges of said tooth bars being bent to form marginal flanges and the teeth on said bars being formed from the portions of said bars between the flanges thereon and being arranged substantially in theplanes of said marginal flanges, and'a-transverse support or supports intermediate said end frame members provided with slots Which receive the marginal flanges on said tooth bars, and means for connecting said tooth bars and intermediate transverse supports, substantially as described.

In testimony, that I claim the foregoing as my invention, 1 affix my signature in presence of two subscribing Witnesses this 14th day of November, A.'D., 1912.
